The design is come from Long Tran of YankoDesign:

Each pod holds 7 wireless bluetooth speakers. Only one possesses the one ring to rule them all because it controls global volume. Each sphere is powered by a lithium ion rechargeable via induction when placed in the pod. The system doesn’t do surround sound since it can’t separate channels, but it’s a good way to fill a large area with a mixed stereo track

7 channel surround sound? What a great design...
